Answer:
420 ways
Step-by-step explanation:
According to the given statement:
We want to divide the 10 dogs into three groups, one with 3 dogs, one with 5 dogs, and one with 2 dogs. How many ways can we form the groups such that fluffy is in the 3-dog group and nipper is in the 5-dog group.
In this way we have 8 dogs left.
2 spaces left in 3 dogs group
4 spaces left in 5 dogs group
and 2 spaces in 2 dogs group
Therefore:
= 8!/2!4!2!
= 8*7*6*5*4*3*2*1/2*4*3*2*2
= 8*7*6*5/2*2
= 1680/4
=420
It means there are 420 ways to from the groups....
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
Rate at which Alina swim = 2.5 miles per hour
Rate at which Talia swim = 1.8 meters per second
First we need to change meters per second into miles per hour
As we have given that
and
So, to change into miles per hours, we'll apply this,
So,
Difference between their rates will be given by
Hence, Talia swims about 1.5 miles per hour faster than Alina.
So, Option 'D' is correct.
